CROWN-CAP AND REMOVAL MEANS Filed July 8, 1964 //YVEN 7 025 MO./(0/7dak0w Jame: W ng United States Patent Ofiice Patented Jan. 17, 1967 3,298,555 CROWN-CAP AND REMOVAL MEANS Mikolaj 0. Kondakow, 185 Clavet St., and James Wong, 14 Hodge St, both of Port Arthur, Ontario, Canada Filed July 8, 1964, Ser. No. 381,077 3 Claims. (Cl. 215-69) The present invention comprises a crown-cap and means for removing same from a bottle after being crimped thereonto, an object being to provide a combination of the character herewithin described by means of which the use of a conventional, or any separate, form of cap remover is rendered unnecessary.

A further object is to provide a combination of the character herewithin described which is effective, commercially acceptable in appearance, simple to operate and low priced in respect to fabrication costs.

With the foregoing objects in view, and such others as may become apparent as this specification proceeds, the present invention consists of the following arrangement and construction of parts all as hereinafter more fully described, reference being had to the accompanying drawings in which:

FIGURE 1 is an external plan view of the present invention.

FIGURE 2 is a side elevation of the present invention partly fragmented.

FIGURE 3 is a representation of the manner in which the present invention is used.

FIGURE 4 is a plan view representing the form of cap bifurcation effected by the use of the present combination.

In the drawings, like characters of reference designate similar parts in the several figures.

The combination of parts which comprises the present invention consists of a crown cap collectively designated 1. The same is provided with the conventional form of crimped skirt collectively designated 2 and is intended to be applied to a bottle 3 in the usual manner.

The cop 1 is however characterized by being provided with a pair of parallel and spaced substantially diametrical lines of weakness 3 defining a parting strip 4 therebetween. The lines of weakness aforesaid appear on the interior or under-surface of the cap, and near one end thereof an aperture 5 is provided.

The central portion 6 which is the portion at least predominently inscribed with the aforesaid lines of weakness is provided with an externally projecting concentric, an-' nular flange 7, which provides with the surrounding land 8, a shoulder for the snug and neat-looking accommodation of the finger-piece collectively designated.

The means for removing the aforesaid crown cap comprise a fine, steel cutting wire, or parallel portions of steel cutting wire, such as musical string wire of round or triangular cross-section, together with the aforesaid finger-piece 9. The aforesaid wire collectively designated 10 comprises the two parallel lying portions 11, the ends 12 of which are anchored as by means of spot welding 13 to the interior surface of cap 1 adjacent or upon the skirt 2 thereof, at the opposite end of the lines of weakness 3 to those near which aperture 5 is located, and preferably at the edge of the skirt 2 as best illustrated in the accompanying FIGURE 2.

The strands of wire 11 lie parallel with and against the parting strip 4 (or adjacent the single line of weakness 3,

if there is only one such line). Wires 11 emerge through aperture 5. At the point of such emergency they divide as best illustrated in the accompanying FIGURE 1 to form a ring (already designated as finger-piece 9). The ring portion is preferably covered with material such as plastic 14 for protection of the fingers.

Having thus described the present invention, its manner of operation will readily be apparent by best reference to the accompanying FIGURES 3 and 4. From the former of these two figures it will be recognized that in order to remove the cap 1, the finger-piece or ring 9 is removed from its described seating, and simply pulled. This has the effect of ripping the cap diametrically into the two parts 15 of the accompanying FIGURE 4, as from aperture 5, to the spot-welded anchorage point 13. As the two parts 15 are ripped apart, they separate; hence, obviously the cap comes off as illustrated in the accompanying FIGURE 4.

By reference to the accompanying FIGURE 2 it will be observed that a liner 16 of cork or the like extends over the wire cutting portions 11, and over aperture 5 so that the contents of the container 3 remain effectively sealed therein until the cap is removed.

Since various modifications can be made to the novel subject-matter herein, without departing from the inventive concept which the same embodies, it is not intended that protection of this invention by Letters Patent should be interpreted as restricted to the particular modification or modifications thereof particularly described and exemplified.

What we claim as our invention is:

1. In combination, a crown-cap having an externally projecting, concentric, annular flange formed therein, and means for removing same from a :bottle after being crimped thereonto, said cap being provided with a diametrical line of weakness, and apertured near one end of said line, said means comprising a steel wire anchored to said cap near the opposite end of said line of weakness, and spanning said cap parallel to said line adjacent the interior surface of said cap, said wire extending through said aperture and terminating in a finger-piece on the exterior side of said cap in the form of a ring normally surrounding said flange, being held in position thereby, and a sealing liner covering said steel wire and said aperture.

2. The combination according to claim 1 in which said wire is anchored to said cap at both ends thereof, and spans said cap in duplicate, said ring being formed of the looped end of said wire.

3. The ring according to claim 2 in which said looped end is covered to protect the fingers.
